Subject: igb: warn if max_vfs limit is exceeded
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b082d734a938b951ed4b9b5a850ae3513d4a7e3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

igb: warn if max_vfs limit is exceeded

Currently there's no warning printed when max_vfs > 7 is specified with
igb and the maximum of 7 is silently enforced. This patch prints a
warning and informs the user of the actions taken.
